The main reason is probably that the UC3 header files in the GCC or IAR delivery are out of date.
Check the header files patch procedure on the installation page.
The Control Panel firmware on the EVK1100 is named "EVK1100 control panel".
It is part of the UC3A software framework package and can be found under X.Y.Z-AT32UC3A/APPLICATIONS/EVK1100-CONTROL-PANEL/.
A default .elf file is provided (named uc3a0512-ctrlpanel.elf) in the UC3A Software Framework package and can be found under X.Y.Z-AT32UC3A/APPLICATIONS/EVK1100-CONTROL-PANEL/AT32UC3A0512_EVK1100/GCC/.
avr32program program uc3a0512-ctrlpanel.elf -e -v -R -r -finternal@0x80000000,512Kb
make program reset run
This will compile and link the Control Panel, program it to target, reset the target then run the new firmware.
The firmware is now updated.
This warning is a known issue and it doesn't prevent the firmware from running on target correctly.
When using the default linker scripts provided with avr32-gcc, the ELF LOAD program headers are generated automatically from the output sections, including BSS and the stack which are only allocated areas.
In its current revision, avr32program programs allocated LOAD program headers that do not have to be filled with data from the ELF file, which is wasting programming time.
This behavior of avr32program will be changed in a future release, but until this is achieved, the linker scripts provided with the software framework are changed to place the allocated-only output sections in NULL ELF program headers ignored by avr32program, hence the warnings when linking.
This can be done using command line tools to convert a binary file into a hexadecimal table.
Open a shell and make sure you have the following tools available: od and sed. If you have
Cygwin (http://www.cygwin.com/) installed, these tools should
be present by default.
Type the following command line, where binary corresponds to the path of the binary file you want to convert.
od -A d -t x1 -w16 binary | sed -e 's/[0-9]*//' -e 's/[\ ]*\([0-9a-f]\+\)/0x\1, /g'
This command will output raw hexadecimal data which can be paste in your project and used as a unsigned char table.
